Kevin here from S/V Bladerunner, the Wildcat 350. Thanks for the shopping me the battery combiners. Bought both for $20. Wanna make sure they both work before installing. Strange how he didn't want to use them and go back to just a one bank system. Question, do you Eileen from the Manta Perseverance? I was told that they're looking for a smaller cat and wanted to let them know about our boat. Since they're in town it would be worth showing them Bladerunner. You can reach me on my cell phone at 321.693.1642. Thanks again Mark and Happy 'n Safe Sailing! Kevin
